If the USB device is dedicated to the guest while it's running, then USB support, in general, is whatever the guest O/S supports.
If the USB is proxy-passthrough (that is, the host recognizes the device, then passes it off to the guest), then support is whatever the host (Linux) supports.
In either case, the speeds may be a bit low and most full virtualization systems (e.g. KVM, Virtualbox, VMWare) have issues with I/O performance and occasional twilighting (the VM may pause for several seconds) that can interfere with realtime services like recording Video.

Not sure, have you looked at MythTV?

 Would that program be able to import/view MKV files?

MKV is an open container, so good there.  Most Linux distributions handle h.264 video and MP3 audio just fine.

Depending on the file format, this may be recoverable/migratable, pull the database into Linux and try to open it with sqlite3 or a text editor (might be SQLite or XML), if that doesn't work you might do some google searching for software to interpret/migrate the data.
